Hi Bastian,
Thanks for your reply.
I use a XCVR2450 with an N210. Up until now I did not do any real
performance measurements, but with the PCAP output it sould be easy to
quantify your losses. You can just open the PCAP file, with Wireshark for
example, and immediately see how many packets
Hi Bastian,
I played a bit with your examples. The tx all works perfect. But for rx,
sometimes I get the hello gnuradio messages, sometimes not. What
daughterboard are you using, I use the RFX2400.

Cool, that it compiles and at least does
Hi Bastian,
Now the grc examples work with no error. The crash of the system during
gnuradio compilation is due to the boost version (the version 1.46 causes
the problem). After I switched to version 1.48, the compilation of the
current gnuradio from the git repository works all right.

Hi Bastian,
I am newbie to USRP and Gnuradio. I did make and make install of your
project. But when I opened the rx.grc, I got some errors. Could you please
take a look what is the cause for that?
Thanks in advance.

Hi Bastian,
I am using Ubuntu 12.04. I first try to compile the gnuradio with
build-gnuradio script. But the system crashed after starting making
gnuradio.
So later I use the precompiled gnuradio and uhd directly from ettus. It
seems that the gnuradio is install in the folder
Hi all,
I played a bit around with the 802.15.4 blocks [1]. Maybe someone is
interested.
The changes are:
- It has a transceiver flow graph. (That was really easy with the new
PDU to tagged stream block)
- annotate LQI value in dict of PDUs
- CRC check
- Wireshark Connector. You can write
